From 1905 to 1970, this structure was known as the Recitation Building and housed the classrooms for basic subjects. The building was renovated in 1988-89 and was named in honor of William D. Shambaugh, a distinguished alumnus. 

It now houses the Dr. Ralph W. Ketner School of Business, the offices of the President and vice presidents, the Alumni and Institutional Advancement offices, the Mark I. Forman Reading Room, the Wayne A. Champion Lounge and the GTE Telecommunication Classroom.
